Scott, When I first saw it I thought it may have been a Lombardy poplar but it does not have a slender form. It's definitely not a cottonwood. According to my Audubon Field Guide it has the form of an aspen. The leaf is paler on the bottom and its stem is slightly flattened. It also feels a little leathery. The bark is not white like a european white birch but a greenish yellowish white color. Whatever they are they were planted in a straight line and evenly spaced along the trail. I had a camera but I left it in my truck. I keep forgetting that my cell phone can take pictures also.

George Nice report. Any chance the quaking aspen is a cottonwood or a hybrid poplar? Don't see too many quaking aspens around here. Did it have white bark?
